Late-onset toxic anterior segment syndrome after possible aluminum-contaminated and silicon-contaminated intraocular lens implantation.

Purpose: To describe an outbreak of late-onset toxic anterior segment syndrome (TASS) after the implantation of a specific hydrophilic acrylic intraocular lens (IOL).

Setting: University Hospitals of Leuven, Belgium.

Design: Retrospective, single-center, observational study.

Colour contrast thresholds are normal in functional amblyopia.

We evaluated colour contrast thresholds in patients with unilateral functional amblyopia. A computer-controlled colour vision test was used to determine colour contrast thresholds along a blue-yellow tritan axis. Prior to the threshold measurement, a heterochromatic flicker brightness test was performed to ensure isoluminance between the test stimulus and the background for every subject individually.

Ocular toxocariasis in a 36-year-old patient: a case report.

A 36-year-old female presented wit unilateral papillitis, followed by the development of a posterior pole granuloma. A positive ELISA-test for toxocara canis with a titer of 1/200 established the diagnosis. The patient was consecutively treated by pars plana vitrectomy and oral corticosteroids.
